Q. Could you please tell me how to calculate how my CSRS annuity would change if my wife predeceases me? I have elected a full annuity for her (I retired in 2006). I assume that my annuity will increase if she dies first, but I do not know how to figure the increase.
A. Your annuity would return to what it would have been had you not elected a survivor annuity. That original amount would be increased by any cost-of-living adjustments you have received since you retired.
